aesthedes graphical supercomputer

Aesthedes:

The Aesthedes was one of the earliest graphics supercomputers for vector drawings, in the eighties. It was mostly used for product design (in 2D) and packaging design. Thanks to its innovative keyboard with 500 logically grouped keys with LED-lamps, you could design very fast on the Aesthedes: you kept one hand on the mouse while drawing. And with the other hand you selected the desired key, without taking your attention off the design. This is contrary to most "modern" computers where the creative process is interrupted 10 000 times, to mess around with annoyances like menus, toolbars, dialog boxes, curve-handles, and where you have to memorise hundreds of shortcuts which differ from program to program...

However, price was prohibitive: depending on the options (cameras, scanners, A0 pen plotters, cutting plotters, huge inkjet and thermal printers, film recorders, huge tape-drives, laser plotters,...), the price-tag of an Aesthedes system was usually between 200 000 and 500 000 euros. Electronic stability was not great: due to its 30+ printed circuit boards, and 30+ flatcables, it was sensitive. The "software" was actually firmware, stored in eprom, closed source. Text-setting was primitive, since it was not designed for that. These drawbacks meant the end of the Aesthedes, when the much cheaper Apple Mac (ca. 20 000 euro) came on the market, with a relatively open operating system on which you could run software from multiple vendors like Adobe and Corel Draw, and with much better text-setting abilities.

In this image you also see a few vector drawings created on an Aesthedes computer, around 1986. The yellow car and KG-logo are my own designs. The dinner plate and cup in the sun are a famous vector drawing by Steve Sherer, after a photo by Paul Hoffman. The futuristic car in orange-purple probably is from a Dutch designer; the Oldy is from a Belgian artist; and the Jaguar is from an English or American artist, maybe from the Pasadena Art Center College of Design (?), but I don't know their names. The Aesthedes-logo is from Dominique Claessens, in the Netherlands, inventor of the machine.

My profile-photo artwork (at the top left of this page) was also designed on the Aesthedes: a photo was scanned, edited, desaturated, posterised (=reduced into 4 levels), vectorised, and printed on a Versatec color printer. This is a scanned image of a Versatec print, as the original electronic data do no longer exist.

This page contains manuals on 3D-printing, and several 3D-models that you can print yourself. Mostly related to the Ultimaker2 printers, but some methods or ideas might be useful for other systems too.
